[snip] River Mile 232 is where Glenn and Bessie Hyde lost their lives. The Kolb Brothers found their unoccupied Drift Boat there in an eddy. [/snip]
Somehow I got recommended to the 411 Missing People Reports on Youtube - people vanishing in the wilderness. Or found 10 miles away in good condition in rugged terrain and terrible weather. Maybe Glenn and Bessie were the first!?
Makes for interesting campfire stories. My campfire stories out in the woods usually centered around Bigfoot. Kind Bigfoot when the kids were little (rescuing a lost child, etc.) and as the kids got older, Bigfoot got a bit more menacing - but it was just because he wanted to be left alone.
